render-background-workers

Background workers on Render run queue-based services for asynchronous job processing using frameworks like Celery, Sidekiq, or BullMQ. You configure the worker, a Redis broker, and a render.yaml blueprint to deploy and verify graceful shutdown behavior.

Graceful shutdown on Render is handled using SIGTERM and configuring maxShutdownDelaySeconds. This ensures long-running tasks in background workers complete or terminate safely before the service shuts down.

Use background workers for queue-based asynchronous tasks triggered by events, and cron jobs for scheduled tasks. The Skill provides guidance on choosing between workers, cron jobs, and workflows for scalable async processing.

Yes, Render supports queue-based background workers across popular frameworks including Celery, Sidekiq, BullMQ, Asynq, and Oban. These frameworks connect to a Key Value Redis broker for asynchronous job processing.

To set up a BullMQ worker on Render, you need a Render project, a Key Value Redis instance as a broker, and a render.yaml blueprint for worker configuration. This enables asynchronous task processing and graceful shutdown.

A Redis broker is needed on Render to queue and distribute asynchronous jobs to background workers. The Key Value service acts as the message broker connecting your application to worker frameworks like Celery or Sidekiq.
